Abstract
A flow control device for a fluid flow system includes a conduit having a cylindrical insert member disposed within. The insert member includes an axially-extending depression, and a flow bypass channel of progressively increasing cross-section within the depression. A roller mounted for movement along the wall compresses the wall into the depression to restrict flow to the underlying portion of the bypass channel. By positioning the roller the operative area of the bypass channel is varied to obtain a desired flow rate.
